This invention relates to an electrical cable connector and more particularly relates to a connector for a coaxial cable. Y

Electrical cable connectors used in aircraft and many industrial applications must bte easily operated even though provision is made to prevent random physical shocks and vibrations from interrupting continuity of electrical service through the connector. This is also true regardless of the physical size of the connector. In the past it has been experienced that miniaturized connectors, which are shock and vibration resistant, have oftentimes been diiiicult to operate. Where size is critical it is no solution to merely make the connector larger, thus enabling easier physical handling or manipulation of the parts.

With these comments in mind it is to the elimination of these and other disadvantages that my invention is directed, along with the inclusion of other new and novel advantages.

An object of my invention is to provide a new and improved electrical connector of relatively simple and inexpensive construction and operation.

Another object of my invention is the provision of a novel shock and vibration-resistant electrical connector which lmay be readily and easily operated to effect connection and release of the several parts.

Still another object of my Iinvention is the provision of a novel electrical connector which is well adapted for miniaturization and which is well'adapted for convenient and easy connecting and disconnecting even in miniaturized form.

A further object of my invention is to provide an improved and novel electrical connector which may be readily and easily connected to a coaxial cable so as to prevent any moisture migration along the cable and to the contacts of the connector.

These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to similar parts throughout the several views and in which:

The electrical connector includes a female component or part, indicated in general by numeral and a male component or part, indicated in general by numeral 111. The male component or part 111 includes a male body sleeve 112 confining an insulating sleeve 113 and acontact pin 114 electrically connected to a conductor element 115, which in the form shown comprises a rigid wire terminal bar, but could well be a cable secured to the male body sleeve in a manner similar to the mounting of the conductor 116 to the female component 11). In the illustrated form, the male component 111 is adapted for mounting on a panel and is provided with an exterior protruding liange 117 and securing means 118 disposed rearwardly thereof and taking the form of a groove or shoulder for receiving a retaining ring therein for clamping the panel against the ange 117.

The male body sleeve 112 has a pair of outwardly protruding bayonet pins 119 adjacent the front end thereof and the male body sleeve also has a resilient sealing ring 120 on the exterior periphery thereof disposed slightly rearwardly from the bayonet pins 119.

The coaxial cable 121 to which the female component 110 is connected includes the conductor 116, the inner primary insulation 122, the metallic braid 123 and the outer secondary insulation 124. It wil-l be seen that the secondary insulation 124- is terminated adjacent the point at which the braid 123 is folded back upon itself and anchored to the female component, and the .primary inner insulation extends forwardly, substantially to the terminal end of the conductor 116 which is soldered to a socket Contact 125 which is adapted to receive the pin contact 114 of the male component.

It will be understood that all of the elements and parts hereinafter mentioned of the female component 110 are circular in shape and are concentrically oriented with respect to an axis defined by the conductor 116. The female component 119 includes a female body sleeve 126 having a smooth and cylindrical exterior surface along the intermediate and rear end portions thereof and also has an enlarged forward end portion 127 wherein a plurality of inwardly biased spring fingers 128 are formed integrally for producing a sound electrical connection between the female body sleeve 126 and the male body sleeve 112 when assembled therewith. The female body sleeve 126 has an abrupt rearwardly facing shoulder surface 129 at the rear end of the enlarged forward end 127 thereof, and the female body sleeve also has a plurality of circumferentially spaced and longitudinally extending bayonet pin-receiving slots 130 extendingl entirely from the abrupt shoulder 129 to the front surface 131. The female body sleeve also defines an internal forwardly facing seating surface 132 disposed slightly forwardly of the abrupt shoulder 129 for mating in end-to-end relation with the front surface of the male body sleeve 112, with the resilient gasket 133 disposed therebetween in sealing relation.

It will be noted that the front end 127 of the female body member 126 has recesses 134 at the sides of the .bayonet pin-receiving slots to receive the bayonet pins in captured relation.

The recesses 134 are normally obstructed by the forwardly projecting lugs or lingers 135 which lie in and substantially lill the slots 130. The fingers or lugs 135 are mounted on and formed integrally with a rigid mounting ring 136 which is slidably mounted on the reduced intermediate portion of the female body sleeve 126. A coil spring 137 on the female body sleeve 126 bears forwardly against the ring 136 and is anchored against rearward movement by a rigid guide ring 138, which, in turn, is anchored against rearward movement by a snap ring 139 lying in a shallow exterior annular groove 140 in the outer periphery of the female body sleeve 126, the groove 140 appearing in FIGURE 6. It will be noted that the spring 137 permits sufiicient rearward movement of the ring 136 as -to permit the lugs 135 to move out of obstructing relation with the recesses 134, thereby permitting the bayonet ears 119 to be released for removal from the slots 130. However, the convolutions of the spring bottom against each other to prevent excessive rearward movement of the ring 136 and to prevent the fingers 135 from sliding rearwardly out of the slots 130.

The female component 110 also includes an outer movable sleeve 141 encompassing and confining the intermediate and rear portions of the female body sleeve 126, the ring 136, spring 137, guide ring 138 and retaining ring 139. The rear end of the outer sleeve 141 may extend rearwardly to the retaining nut 142 which carries a resilient sealing ring 143 and engages the rear end of the sleeve 141 in moisture-sealing relation.

The outer sleeve 141 also includes an inwardly protruding annular flange 144 disposed between the ring 135 and the abrupt shoulder 129, and having a pair of openings 145 (see FIGURE 4) therein slidably receiving the lugs 135 therethrough and permitting relative movement l between the lugs 135 and the outer sleeve 141.

The outer sleeve 141 is slidably mounted on the guide ring 138 and has a forwardly extending skirt portion 146 slidably mounted on the front end 27 of the female body sleeve, and the skirt portion 146 protrudes endwise forwardly from the front end of the female body sleeve and normally lies in sealing engagement with the resilient sealing ring 120 on the male component 111. It will be noted that a portion of the exterior surface of the outer sleeve 141 is knurled such as at 147 to permit a person to readily and easily grip the outer sleeve and move it endwise rearwardly against the action of spring 137.

In the operation of the male and female components in connect and disconnect operations, it will be seen that where, as in the present situation wherein the male component is assumed to be mounted on a panel, a person need merely grip the outer surface of the outer sleeve 141 with one hand and move the female component 110 into endwise assembly with the male component 111, by guiding the female body sleeve 126 into encompassing relation with the male body sleeve 112 and aligning the slots 130 with the bayonet pins 119. Because the spring 137 normally urges the ring 136 to a forwardly disposed position wherein the lugs 135 are in obstructing relation with the recesses 134, the bayonet pins 119 of the male component will engage the front vbeveled ends 135a of the lugs and cause the lugs 135 and ring 136 to move rearwardly with respect to the female body member 128 to the position wherein the recesses 134 are unobstructed. During this entire operation, only one hand need be used in gripping the outer sleeve 141 to urge the entire female component 110 in a forward direction. When the bayonet pins 119 have been moved into confronting relation with the recesses 134, a slight turning of the outer sleeve 141 will cause a similar turning of the female body sleeve 126, thereby causing the bayonet pins 119 to move into the recesses 134, whereupon the action of spring 137 causes ring 136 and lugs 135 to move forwardly so as to again obstruct the recesses 134 and effectively capture the bayonet pins 119 therein. During this forward movement of the female component 110 with respect to the male component 111, the forward end of the outer sleeve 141 will be moved into encompassing and sealing relation with the sealing ring 120 on the male component so as to seal the entire apparatus confined within the outer sleeve 141 against contamination due to moisture, dirt, dust and the like.

1t will be noted, as `a practical matter, the assembly of the female component with the male component 111, merely involves the guiding of the outer sleeve 141 into encompassing relation with `the sealing ring and the orienting of the component 110 so that the slots 130 receive the bayonet ears or pins 119, and the person effecting the connection need be concerned with nothing else whatever. During the time when the female component 110 is being moved forwardly over the male cornponent 111, the person effecting the coupling needs to perform no operation whatever except the producing of a forward movement. The beveled ends a of the lugs 135 cooperate with the bayonet pins 119 causing relative rotation of the female component so that for all practical purposes the coupling is effected by a straight forward movement, plus a very slight rotation to move the bayonet pins 119 into the recesses 134. Simultaneously, the socket contact 1275 is moved into encompassing and electrically engaging relation with the pin contact 114 so that the electrical connection is completed. v

In the disconnect operation wherein lthe female and male components 110 and 111 of the connector are to be Separated, the outer sleeve 141 will again be merely gripped with one hand and will be pulled rearwardly away from the fiange 117 of the male component 111. The rearward movement of the outer sleeve causes a correysponding rearward movement of the ring 136 and lugs 135 lwhile the body sleeve 126, at least temporarily remains stationary. When the lugs 135 move past the recesses 134 so as to remove the obstruction in front of the recesses 134, the body sleeve 126 will start moving rearwardly, and the ramp surfaces of the recesses 134 will cause a slight rotation of the entire female component 110 Aas the bayonet pins 119 move along these ramp surfaces so as to produce a camming effect which causes the rotation of the female component 110. The bayonet pins will then pass along the slots 130 as the female component 110 is moved away from the male component 111. It will therefore be seen that as a practical matter, the outer sleeve 141 need merely be gripped and pulled away from the male component 111 so as to effect the disconnect action.

In relation to the clamping of the coaxial cable 121 to the female component 110 and the connection of the braid and central connectors 123 and 116 respectively, it will he seen that an insulating sleeve encompasses and confines the socket contact 125 and is provided with suitably arranged shoulder surfaces to abut against corresponding shoulder surfaces of the socket contact 125 and ofthe female body sleeve 126 so as to prevent forward movement of the socket contact 125 and Ithe insulating sleeve 150 with respect to the female Ibody sleeve 126. The rear end of the insulating sleeve 150 extends rearwardly beyond the contact element 125 and extends to a rearwardly facing abutment shoulder 151 against which an anchor sleeve 152 bears. The outer cylindrical periph- 'eryof the conductive metal anchor sleeve 152 lies flush against the inner periphery of the female body sleeve 126; and the inner periphery of the anchor sleeve 152 is conically -tapered and converges in a forward direction. A braid-clamping sleeve 153 has the metallic braid 123 folded around the front end thereof and mates together with the anchor sleeve 152 in wedging relationship so as to clamp the end of the braid 123 therebetween in a strong physical relationship and a sound and stable elecltrically conductive relationship. The cable-clamping sleeve 153 has` a generally cylindrical and threaded interior periphery which screws onto the resiliently yieldable secondary outer insulation 124 of the cable and produces a moisture-sealing relation therewith, and the outer periphery of the cable-clamping sleeve 153 is conically tapered and converges in a forward direction, substantially conforming to the taper of thc inner periphery of the anchor sleeve 152 so as to efficiently wedge the end of the braid 123 therebetween. At the rear end of the cableclamping sleeve 153, an annular knife-edge 154 is defined to engage and cut through a resiliently compressible and yieldable sealing gasket 155, which is caused to compress rmly against the outersecondary insulation 124 of the cable and against the inner periphery o-f the body sleeve 126. The gasket 155 is urged forwardly and against the annular knife edge 154 at the rear end of the sleeve y153 by a ywasher 156 and a nut 142 which is threadably secured to the rear end of the body sleeve 126.

A substantially rigid insulating ring 157 lbears forwardly against an interior shoulder surface of ythe insuia tion sleeve 150 and also bears forwardly against the rear end of the contact element 125 for maintaining the contact element 125 and the insulating sleeve 154i in predetermined relation with each other. The insulating sleeve 7 essentially comprises a portion of the insulating sleeve 151B in an operational sense and bears rearwardly against a resiliently compressible sealing gasket 158 which also bears against the forward end of the cable-clamping sleeve 153 with the braid 123 wrapped therearound so as to be caused to deform outwardly and inwardly against the rear end of the insulating sleeve 15) and against the inner primary insulation 122 respectively, thereby establishing a moisture-sealing relation between the inner primary insulation 122 and the insulation sleeve 156 to prevent moisture migration longitudinally therebetween.

The conductor 116 is inserted into a recess at the rear of the contact element 125 and is soldered therein to produce and maintain a sound and sta-ble electrical connection.

It will be seen that the braid 123 of lthe cable is electrically connected to the male body sleeve 112 through the medium of the cable clamping sleeve 153, anchor sleeve 152, female body sleeve 126 and the resilient spring lingers 128.

Moisture migration to the contact element 125 and pin contact 114 is prevented through the cooperation of the sealing rings 120 and 143, the gasket 155, the sealing ring 158, and the resilient gasket 133 which engages the end of the male body sleeve 112. V

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of the invention which consists of the matter shown and described herein and set forth in the appended claims.
